Pocket money, or the money that someone gives you will only bring you unrest mind if you plan to invest with such money, it's the type of money you are not ready to lose, because it's all you have, because you have no other money coming from else where.
You don't need Bitcoin first, What you need is a JOB, work on that first.
It's true, having a job with a regular monthly income is much more important that buying a few hundred USD worth of bitcoin. Having a small crypto portfolio is not going to much us rich, even if we trade well and make 50-100% return in a year is not going to let us live independently. The first step should always be finding a job that pays us decently and let's us save money every month. Once we have free disposable income that is not borrowed or needed for medium term purchases, we can start buy crypto currencies regularly. Like that we will be able to build a crypto portfolio much faster. To live off a investment portfolio alone we first need the foundation to start investing. Without any savings it's hard to make large returns.
